bi; Application tiled August 8, 1894:. Serial No. 519,768. (No model.)

To @ZZ whom, t may concern: v

Be it known that I, PERRY H. CAZIER, a citizen of the United States,residing at Nashville, Barry county, Michigan, have invented a new anduseful Sickle-Grinding Machine, of which the following is aspecification.

My invention relates to sickle-grinding machines, and its object is toprovide a machine of this character in which the frame carrying thegrinding-wheel is so constructed and arranged as to be adjustable andfreely movable in such a manner as to enable the Work of grinding to beproperly, easily and quickly performed. v

To this end my invention consists in the construction and arrangementsubstantially as herein described, and particularly defined in theclaims.

In the drawings, Figure l is avertical side View of the entire machine.Fig. 2 is a top view thereof.

The base-plate B E is adj ustably secured to any proper supportAby meansof the pivot B' and the slot O O and binding-screws C O. To this base ispivoted, as at Dll D", the upright D. A suitable handle D is secured tothis upright D by which it is controlled.

To the upper extremity of the upright D is pivoted the frame F, carryingthe grindingwheel M. The geared driving wheel K is sleeved in the upperextremity of the upright D land its shaft H serves as the pivot uponwhich the frame F swings and by which said frame is connected to thesaid upright D.

rlhe frame F is forked at its lower end and a grinding-wheel M of anysuitable material is journaled in the arms of said fork. A smallgear-wheel K is sleeved upon the shaft of the grinding-wheel and mesheswith the drivinggear.

An adj listing-screw l, threaded through the frame F, bears upon a smallprojection J formed on the upright D and permits the proper adjustmentof the frame F and consequently the grinding-wheel to the work.

A tension-spring G secured to the base-plate passes through an openingin the upright D and is suitably connected with the frame F. Suitablemeans is provided for regulating the tension of said spring G. Thisconstruction and arrangement regulates the pressure of thegrinding-wheel upon the work While in operation and holds said wheel outof the way while through the countersunk hole N2 and the bolt Q and slotN.

The portion O of the plate N which projects under the grinding-wheel isprovided with a V-s'haped notch and is beveled upon its upper surface soas to provide a proper slant to the sickle while being ground.

The plate N is provided with a lever P ec centrically pivoted thereto,so as to hold the sickle-bar in its proper position on the said platewhile being'ground. The pivot-screw P of said lever is provided with abinding-nut. The plate N is also provided with a small slide Q thatworks over the slot N', and is adapted to be held in its proper positionby means of the bolt Q and a binding-nut thereon. The said slide Q isintended to steady the sickle-bar while being placed in the position tobe ground. j

The base B E and the plate N having been properly adj usted withrelation to each other, the work to be ground is placed upon the plate Nand clamped in proper position by the lever P. The operator thenadvances the frame carrying the grinder with one hand by means of thehandle D', while with the other hand the' driving-gear is operated, thusrotating the grinding-wheel.

What I claim as my invention is- 1. In a sickle grinding machine, thecombination with a base plate of an upright pivoted thereto and providedwith an opening, a frame pivoted to said upright, a grinding wheeljournaled in said frame, a gearsleeved upon the shaft of the grindingwheel and provided with a collar, a driving gear meshing with said gearwhereby the grin ding wheel is actuated, a tension spring carried bysaid frame, eX- tended through the opening in the upright and secured tosaid base plate, means for regulating the tension of said spring and anadj usting screw threaded through the frame and bearing upon theupright, whereby the pressure of the grinding wheel is regulated whenlooking said lever in its operative position, an adjustable guidecarried by said plate and means whereby said guide is looked in itsoperative position, the construction and arrangement being suoli thatthe Work is firmly held to the grinding Wheel and the operator free torotate said Wheel.
